sTrTcHING-MACHINE GUARD.

- Application filed January 10, 1921,.` SerialNo. 436,281.

.2 '0 all whom t may conce/rn.' 1 Y Be it .known that I, TANNS.r C. GUsnMAN, a citizenv of the United States, residing at Houston, Harris County, Texas, have in@ vented a certain new and useful Improvement in Stitching-Machine Guards, of which the following is a full, clear, `and enact description, suchv as will-enable others skilled inthe art to which it appertains to make and 1o luse the same. 4

My invention relatesv to stitching machinev Patent to Ashworth, Serial No. 1,253,331,

issued January 15, 1918.

In stitching soles on slices, a commontype of ymachine used employs a curved needle and awl which, in the sewing operati on, come close to the u per and, unless great care and skill are emp oyed, the upper will be pierced or torn by them so as to injure the shoes. Further, the looper and take-up will come into contact with the shoe uppe-r and smear the same with wax or oil.

The comon type of guard now employed comprises a thin sheet of spring steel or sheet iro-n which is secured to a holder attached to the machine between the take-up and the work. looper and take-up and has to be pivoted so as to be swung out of the Way when access to the named parts is desired.

Furthermore, the guard, when thus placed, interferes with the insertion of the sole beneath the needle. Pressure has to be exerted on the shoe to get the sole in position. This pressure brings the upper against the guard and bends the guard inwardly so far that it often interferes with the operation of the looper and awl. The result is that the guard is usually removed by the operator, who prefers to work without it.

The object of my invention is to provide a device to guard the uppers of shoes from injury, in the use of shoe stitching machines, which will not interfere with the working of the machine. It is further desired to so shape and position the device that it will effectually prevent the upper from injury or mutilation and at the same time will not be inthe way of the operator.

It hides the needle, awl,

, Another object is to do away with the necessity of a holder for the guard and at the .same time v provide asirnple and strong construction.

Referring to the drawing forming a part of this specification and wherein like parts i are designated by likefnumerals of reference throughout the several views, Fig. 1 is a front elevation showingmy guard positioned on a part of a stitching l'machine and showing massa broken parts of said machine sufliciently to p indicate the operation of my invention; Fig. 2 is atop .plan view of my guard; Fig. 3 is a side, or edge view thereof, and F igsgl and 5 are front and side elevations, respectively,

showing a modified form of my invention.

The brokenparts of the Goodyear stitching machine shown inthe drawing are intended merely to indicate the position of my improved guard relative to the needle and looper and to the adjacent p-arts. The guard,

designated lby the numeral 1, comprises a' sheet of spring steel or similar resilient material. lIt is secured by meansof screws 3 and 4 to the gage slide 2, [which in turn is slidably secured on the frame of the machine.4 To the upper end of the gage slide 2 is also secured, by means of the screws 3 and 3', the curved edge gage 5. The needle 6, the presser foot 7, and the work table 8 are shown in their relative positions. Below the table are the looper 9 and the take-up lever 10. i

The particular construction of the preferred embodiment of my device is shown in the three views. The body of the guard 1 has openings or slots 12 therein to receive they screws 3, and 4, by which it is securedy adjustably in place. 'Io hold the plate more lirmly I bend the right hand side of the plate rearwardly at 13, as shown in Fig. 2, to fit around the outer side of the edge gage 5. The upper left hand edge is extended laterally and curved slightly outwardly` to form a lip 11 resting against the outer end of the table 8. I find that if the guard is positioned immediately to the right and in front of the work table 8 the best results are i obtained. Iy have, therefore, designed the guard tobe secured to the gage slide 2 or to the edge gage 5, the object being to secure the resilient guard having the outturned lip ll resting resiliently against the lower edge of the table 8. r[he Work advances under the pressure foot 7 and between the same and the table 8 in a direction from right to left. I vtherefore refer to the'right side of the machine as 'the forward'side. Placing the lip 'l1 of the guard in the position as described and shown will throw the `upper outaway'from thel needle, awl, andv looper tar enough so` that no contaetrorlinjury y tween the said parts and the upper Will take y place. i .v shoe ,easily into the desired position and the 1Q' ontaotof'tlie 'uppervvith the "lip of the A"guardwilly press itout of lthe Way of the y "avvl' and "needleuntil v parts yWhere it Will again assume "form and position.

` shown.

' One is thus enabledxto advaneethe itv hasl passed those its usual is my "object,` thereforeto platee the 'outwardly curved'lip 1l in the vposition taehment te the "gage slide 2. rIt is obvious, however, that "it might `bemuch`shorter than s'how'nfan'dl liind that itmay he seeured'to the lip of .t it to 4bear lightly against vthe forward 'end resilient material andv to position of vthe table@` n t In the modiicatioi'i shown in fli'gs. 4 and 5 there is formed a li" '14 on -thefforward end .of the table 8; yT iis lip as shov'vn v'is a" fiat downwardly inclined projection so pothe'ne'edle' andv avvl and thusv prevent in' sitioned on the tablejas'to bear against the upper and force 1t yaway `c'rorn the path of `jury"Whenfthe Work is being. performed.
